150 years ago: Kellogg brother born -- established Battle Creek, MI as Cereal Production Center

from Writer's Almanac (Garrison Keillor, Am. Public Media):

February 26 is the birthday of John Harvey Kellogg, doctor and cereal pioneer, born in Tyrone, New York (1852). He ran the Battle Creek Sanitarium in Battle Creek,  Michigan to promote healthy living and eating. There, he and his brother, Will, invented several grain-based foods, cooking the grain and forcing it through rollers to make dough. They were cooking wheat one day when they were called away, and when they returned, the wheat was apparently overcooked. They decided to put it through the rollers anyway, and cereal flakes were born.
